This invention relates to improvements in the construction of radiators of the type ordinarily employed'in conjunction withthe cooling systems of internal combustion engines.

The invention has for its object to provide an arrangement of this character in which the tubular parts for conducting the water or other cooling medium are connected with the cooling fins in such manner that these parts are permanently held in position without the use of solder.

A further object of the invention is, the

provision of a radiator construction in whichthe parts. which are preferably formed of sheet metal and constitute the walls of the passage for the cooling medium are formed with corrugations in which the edgesof the cooling fins are located, such portions of the corrugations being subsequently bent V first in one direction and then in another to provide an interlock between the fin parts and the wall parts.

In the accompanying drawings wherein an approved embodiment of the invention is illustrated in the corrugations thereof, prior to the folding or bending of the corrugations.

Fig. 3 is a view similar toFig. 2 showing the corrugations following the folding or bending thereof. l

Referringto the drawings in detail the numerals -5 indicate-sheets of 'm-etalwhichj' in Y the finished radiator, constitute the walls ofth'e passage forconducting the wateror other liquid cooling medium. .The wall members 5 are provided with a'pl-urality'of v spaced parallel folds or corrugations 6','the

corrugations of each plate being arranged in equidistant so that jw'hentwo plates are armar ed side-b side as shown in Fi zl 'lwith the corrugationsprojeeting outwardly, channel's are provided by the corrugationsin which the fins 7 are seated. l The preliminary insertion of the fins is shown at the" extreme top of Fig. 1 and in the partially assembled radiator section in Fig. 2.

Following the insertion of the in the corrugations, the-end portionsD of the lat ter are folded inwardly thr'oiighv the posi= tio'ns B and G, llig; 1 in one direction into facial abutmenfiwith the; wall 'plate'i'5 and the medial portions of the "corrug'a tions arefolded in the opposite direction into fa cial abutment with the wall plate" as ing of the corrugations 5 withthe fins? in serted tliereiniprovides aY fiuid-tight joint betweenthesezpoi tions and due to the lateral bendatthe edges ofthe fins producedwhen folding; the-xcorrugations 6 intofacial abut.-
